The Arch of Galerius and the Rotunda are neighbouring early 4th-century AD monuments in Thessaloniki.
The 4th-century Roman emperor Galerius commissioned these two structures as elements of an imperial precinct linked to his Thessaloniki palace. Archeologists have found substantial remains of the palace to the southwest. These three monumental structures were connected by a road that ran through the arch, which rose above the major east–west road of the city.
The Arch of Galerius was built in 298 to 299 AD and dedicated in 303 AD to celebrate the victory of the tetrarch Galerius over the Sassanid Persians at the Battle of Satala and capture of their capital Ctesiphon in 298. Only the northwestern three of the eight pillars and parts of the masonry cores of the arches above survive.
The Rotunda is a cylindrical structure built in 306 AD on the orders of the Galerius, who was thought to have intended it to be his mausoleum.
The Rotunda has a diameter of 24.5 m. Its walls are more than 6 m thick, which is why it has withstood Thessaloniki's earthquakes. The walls are interrupted by eight rectangular bays, with the west bay forming the entrance. A flat brick dome, 30 m high at the peak, crowns the cylindrical structure. In its original design, the dome of the Rotunda had an oculus, as does the Pantheon in Rome.
After Galerius's death in 311, he was buried at Gamzigrad near Zajecar, Serbia. The Rotunda stood empty for several decades until the Emperor Theodosius I ordered its conversion into a Christian church in the late fourth century. The church was embellished with very high quality mosaics. Only fragments have survived of the original decoration, for example, a band depicting saints with hands raised in prayer, in front of complex architectural fantasies.
The building was used as a church (Church of Asomaton or Archangelon) for over 1,200 years until the city fell to the Ottomans. In 1590 it was converted into a mosque, called the Mosque of Suleyman Hortaji Effendi, and a minaret was added to the structure. It was used as a mosque until 1912, when the Greeks captured the city during the Balkan War. Greek Orthodox officials reconsecrated the structure as a church, and they left the minaret. The structure was damaged during an earthquake in 1978 but was subsequently restored. As of 2004, the minaret was still being stabilized with scaffolding. The building is now a historical monument under the Ephorate of Byzantine Antiquities of the Greek Ministry of Culture, although the Greek Orthodox Church has access to the monument for various festivities some days of the year.
The Rotunda is the oldest of Thessaloniki's churches. Some Greek publications claim it is the oldest Christian church in the world, although there are competitors for that title. It is the most important surviving example of a church from the early Christian period of the Greek-speaking part of the Roman Empire.References:
Craigmillar is one of Scotland’s most perfectly preserved castles. It began as a simple tower-house residence. Gradually, over time, it developed into a complex of structures and spaces, as subsequent owners attempted to improve its comfort and amenity. As a result, there are many nooks and crannies to explore.
The surrounding gardens and parkland were also important. The present-day Craigmillar Castle Park has fascinating reminders of the castle’s days as a rural retreat on the edge of Scotland’s capital city.
At the core lies the original, late-14th-century tower house, among the first of this form of castle built in Scotland. It stands 17m high to the battlements, has walls almost 3m thick, and holds a warren of rooms, including a fine great hall on the first floor.
‘Queen Mary’s Room’, also on the first floor, is where Mary is said to have slept when staying at Craigmillar. However, it is more likely she occupied a multi-roomed apartment elsewhere in the courtyard, probably in the east range.
Sir Simon Preston was a loyal supporter of Queen Mary, whom she appointed as Provost of Edinburgh. In this capacity, he was her host for her first night as a prisoner, at his townhouse in the High Street, on 15 June 1567. She was taken to Lochleven Castle the following day.
The west range was rebuilt after 1660 as a family residence for the Gilmour family.
The 15th-century courtyard wall is well preserved, complete with gunholes shaped like inverted keyholes. Ancillary buildings lie within it, including a private family chapel.
